The Dragunov SVDK large-caliber sniper rifle was developed through "Vzlomshik" (Breaker) research and development program, along with 7.62 mm SV-98 sniper and 12.7 mm ASVK anti-materiel rifles. The purpose of SVDK is to deal with targets which are too hard for standard 7.62ÃÂ54mmR sniper rifles like SV-98 or SVD, such as assault troops in heavy body armor or enemy snipers behind cover. There were also rumors that the SVDK will serve as a long-range anti-personnel weapon.
The effective range of the SVDK is cited as 'about 600 meters'
It has heavy barrel with six right grooves (365mm twist rate), new folding gunstock with rubber recoil pad, a plastic handguard with folding bipod and new standard optical sight.
